    摘要: Various embodiments of the invention relate to bearing assemblies, apparatuses and motor assemblies that include geometric features configured to impart a selected amount of heat transfer and/or hydrodynamic film formation. In an embodiment, a bearing assembly may include a plurality of superhard bearing pads distributed circumferentially about an axis. At least some of the plurality of superhard bearing pads may include a plurality of sub-superhard bearing elements defining a bearing surface. At least some of the plurality of sub-superhard bearing elements may be spaced from one another by one or more voids to impart a selected amount of heat transfer and hydrodynamic film formation thereon during operation. The bearing assembly may also include a support ring that carries the plurality of superhard bearing pads. In addition, at least a portion of the sub-superhard bearing elements may extend beyond the support ring.

    摘要: In an embodiment, a bearing assembly may include a support ring to which one or more superhard bearing elements may be mounted. The support ring may include one or more relief features configured to reduce residual stresses in the superhard bearing elements that are induced by brazing the superhard bearing elements to the support ring, operational loads, other processes, or combinations of the foregoing. Reducing the residual stresses in the superhard bearing elements may help prevent damage to the superhard bearing elements. The bearing assembly may be used in subterranean drilling systems and/or other types of systems.

    摘要: Methods of wearing-in superhard bearing elements over time so that hydrodynamic or near hydrodynamic lubrication of opposed bearing surfaces develops and thrust-bearing apparatuses. In an embodiment, a thrust-bearing apparatus including first and second thrust-bearing assemblies is received or provided. Each thrust-bearing assembly includes a support ring and a plurality of superhard bearing elements mounted circumferentially around the support ring. The superhard bearing elements of each thrust-bearing assembly are oriented so as to be opposed to one another. The thrust-bearing apparatus is operated so as to wear-in the bearing surfaces of both thrust-bearing assemblies such that the bearing surfaces of the superhard bearing elements of each thrust-bearing assembly substantially correspond to one another and become very smooth providing for at least near hydrodynamic operation in which a fluid film is present between the bearing surfaces of the first and second thrust-bearing assemblies so as to limit contact therebetween.
